drop_type(7) [centos man page]

DROP 
TYPE(7)						  PostgreSQL 9.2.7 Documentation					      DROP TYPE(7)

NAME

       DROP_TYPE - remove a data type

SYNOPSIS

       DROP TYPE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TYPE removes a user-defined data type. Only the owner of a type can remove it.

PARAMETERS

       IF EXISTS
	   Do not throw an error if the type does not exist. A notice is issued in this case.

       name
	   The name (optionally schema-qualified) of the data type to remove.

       CASCADE
	   Automatically drop objects that depend on the type (such as table columns, functions, operators).

       RESTRICT
	   Refuse to drop the type if any objects depend on it. This is the default.

EXAMPLES

       To remove the data type box:

	   DROP TYPE box;

COMPATIBILITY

       This command is similar to the corresponding command in the SQL standard, apart from the IF EXISTS option, which is a PostgreSQL extension.
       But note that much of the CREATE TYPE command and the data type extension mechanisms in PostgreSQL differ from the SQL standard.

SEE ALSO

       ALTER TYPE (ALTER_TYPE(7)), CREATE TYPE (CREATE_TYPE(7))

DROP 
TABLE(7)						  PostgreSQL 9.2.7 Documentation					     DROP TABLE(7)

NAME

       DROP_TABLE - remove a table

SYNOPSIS

       DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TABLE removes tables from the database. Only the table owner, the schema owner, and superuser can drop a table. To empty a table of
       rows without destroying the table, use DELETE(7) or TRUNCATE(7).

       DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table. However, to drop a table that is
       referenced by a view or a foreign-key constraint of another table, CASCADE must be specified. (CASCADE will remove a dependent view
       entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)

PARAMETERS

       IF EXISTS
	   Do not throw an error if the table does not exist. A notice is issued in this case.

       name
	   The name (optionally schema-qualified) of the table to drop.

       CASCADE
	   Automatically drop objects that depend on the table (such as views).

       RESTRICT
	   Refuse to drop the table if any objects depend on it. This is the default.

EXAMPLES

       To destroy two tables, films and distributors:

	   DROP TABLE films, distributors;

COMPATIBILITY

       This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the IF
       EXISTS option, which is a PostgreSQL extension.

       ALTER TABLE (ALTER_TABLE(7)), CREATE TABLE (CREATE_TABLE(7))
